Sheppard — who is 5 feet 4 inches tall, weighs 110 pounds and has long reddish hair — was reported missing by her family Thursday morning after she entered the woods near Miller Drive with a book and a cellphone.

Township police started up Tuesday's search efforts with help from the Gloucester County Emergency Response Team, surrounding police departments, the New Jersey State Police Missing Persons Unit and a special search and rescue dog from Pennsylvania, said Washington Township Police Capt. Richard Leonard.

They're focusing on the same area searched last week— a 500-acre wooded area with thick brush and difficult terrain.

"We felt that was the last area that we know she was at, and we haven't located any other areas she may have been at. Even though we had spent 10 to 12 hours out there Thursday and Friday, since it's so thick back there and the terrain is so difficult, we want to try it again to make sure we didn't miss anything," Leonard said.

About two dozen civilians, friends and family of Sheppard, are also on scene handing out missing person flyers in nearby residential areas, he said.

Detectives are also still investigating any other leads to her possible whereabouts. Leonard said Friday there were no indications of foul play in connection to her disappearance.

"We're not going to give up," Leonard said. "We're going to keep doing what we do and hopefully we find her."
